I can bet you it's incompetence. They failed upwards. Sure, protocol is great and universal, but connector is atrocious and it has nothing to do with cost. Few points in favor of this hypothesis:
Initially, the plastic inside the connector was white. They started to use black to denote USB2.0 devices, and USB2.0 rapidly became the standard. They at least tried to do something similar with blue plastic with USB3.0.
It's basically the only example I can think of where the plug and socket are rotationally symmetrical without also being reversible. That's the kind of thing where I ask "did you test this before you shipped it?" Thirty years later we're still plagued by the damn thing.
Right you are. Completely forgot about that. That said, I don't think USB1 was a standard for too long. If I remember correctly it went to 2.0 pretty fast.
If you had Macs, USB 1 was around a lot earlier, and really only good for peripherals and HID for a long time. FireWire and external SCSI drives were necessary because USB 1 wasn’t even viable for anything beyond external floppy drives. USB2 was a boon to external drives and bigger thumb drives, but took a while to arrive at the time.
I don't think I had anything with USB1 in it. Even the early Pentium machines had USB2.
I built a Pentium 2 in 1998 and needed a separate pci card to add usb 1.1 (which was what most early Usb was) USB2 came out in 2000. By then I was ready to upgrade the motherboard and the next one had USB built in, but I can’t remember if it was usb 2 or not, since that might have been late 99
I can't remember either, it's been a while. :)
I agree with most of your post, but micro B is a step too far. That fucking plug was always inserted with the following procedure:
Always, always, always.
D
Mini B was rated for something like 10x fewer insertion cycles than micro B, the retaining tabs would give out and the connector would fall off... or worse, twist and break the socket's inner plastic bit.
For some reason I always had fewer problems (meaning none) with mini B breaking than with micro B or C breaking.
In my experience, Mini B was mostly used for data transfer, along with some other port to do the charging. Micro B got introduced as the "all in one" data+charging port. I've seen both kinds of ports break, but only the Mini B ones that were also used for charging; the data-only ones, were fine.
My conclusion is that charging ports use more insertion cycles and are more likely to break, and I keep magnetic charging adapters in all of them (as a side effect, twisting the cable or pulling at an angle just disconnects it, instead of breaking the port).
Well, if nothing else it's easier to than type A.
Hindsight is 20/20. You're raising every issue with the original USB plug, then proceed to highlight how they addressed these issues going forward.
You're describing inexperience and calling it incompetence.
AFAIK the real predecessor to USB was Serial cables and those were an absolute shit show. USB set out to create a more usable interface with a lower profile and cheaper cost. In many ways the minor flaws in USB becoming common gripes is USB becoming a victim of its own success. I don't think they originally set out to become a power charging standard so the frequency at which devices were plugged in increased over time .
At least serial cables weren't symmetric, although just barely. AT and PS/2 cables (or any DIN) were much more of a pain for me to plug in blind.
I don't even know that I would call it inexperience. I just think a major part of the first pass was selling the idea of USB. You can design a perfect cable, plug, and protocol, it doesn't mean anyone will use it. Most investors don't know much about the technical details of a product. They do, however, understand the price. If you're trying to make a difference in the world, you don't always get to do it with style and quality.
How lucky you were to never have a device that had one of these upside-down.
Or a printer with the B connector rotated 90° to one side.
